This invention relates toan improved conmember to the end-piece oftheframe porstruction of. temple hinge for an ophthalmic tion by a hinge,and it is found of advantage mounting; and the object of this inventionto form the hinge members of plates having is to provide an improvedconstruction of interlocking, raised ear portions pivotally 6O 5 hingeof this character comprising a pair connected and to imbed the plateportions of of pivotally-connected plates adapted to each hinge-memberin its respective member hinge the -temples to the end pieces of the ofthe mounting, fius'hwith its outer surface, frameand to provide on oneor both of the and also to secure the hinge plate in its plates of eachhinge one or more spurs respective member by means of a single 10 whichextend rearwardly into the lOOfi y of rivet, screw or other astening,and it is the non-metallic member to which it is atfurther found thatwhen so constructed'that tached to assist in retaining or holdinmthe thesingle rivet is insufiicientto hold the vhinge platev in its setposition thereon by hinge plate against unusual strains, and

The hinge-plate 15 is therefore, similarly constructed to be imbeddedinto the inner face of the temple 12 and a single rivet 20 is preferablyemployed for fastening this plate to its temple. 1

These hinge-plates 14L and 15 are each provided with abeveled stop lip21 extending forwardly from the edge of the ears 16 so as to limit theopening motion of the hinge plates beyond a definite ,or predeterminedangle as the projecting stop of one plate will bring up against that ofthe other plate and so limit the opening motion of the two.

It is found in practice that the long leverage of the temple 12 whenengaged by its free end, that great strength in the hinge is required toprevent the imbedded hinge plate 15 from twisting about its single rivetfastening 20 and much trouble has been experienced from the loosening ofthis connection between thehinge-plate and the temple.

Therefore, in order to strengthen this fastening and prevent a relativerotating movement of the temple about the rivet 20, I have turneddownwardly the outer or opposite edges of the stop 21 thus forming apair 0 widely spaced apart spurs 22 on the front end of the plate andthese spurs are adapted to project into the non-metallic stock of thetemple forming a three-point bearing which effectually prevents anymotion whatever of the temple on its hinge-plate 15 at this point.

Another reason for spacing apart these spurs 22 is to cause them tostraddle the hole 23 which extends through the temple for the purpose ofreceiving the wire core 24 thereof, and thus strengthen the end of thetemple against splitting through the opening for the rivet 20.

My improved hinge structure is very simple, practical and inexpensive tomanufacture, the spurs being made from a portion of the stop lip are ofsuch a length as not to project through to the outer surface of thenon-metallic material, and, therefore, are not visible from the outsidethereof and these spurs'are very elfective in stiffening and supportingthe connection of the hinge to the temple member.

The foregoing description is directed solely towards the constructionillustrated, but

I desire it to be understood that I reserve the privilege of resortingto all the mechanical changes to which the device is susceptible, theinvention being defined and limited only by the terms of the appendedclaims.

I claim:

1. In an ophthalmic mounting, a plate riveted in position on the templeby a single rivet, hinge joint eves on the outer S'HIO thereof at thefront edge, and a spur pro-- j ccting inwardly from said pl ate at thefront edge thereof and imbedded into the temple to assist the rivet insecuring the plate in set position therein.

2. A temple hinge mounting, comprising pivotally-connected platesadapted to hinge a non-metallic temple member to its end-piece member, asingle rivet for binding each plate in position, and a fastening spur onone of said plates at the hinge edge thereof adapted to be imbedded intothe member on which it is mounted to assist in holding it in setposition.

3. In an ophthalmic mounting. an endpiece, a temple having alongitudinal opening therethrough, pivotally-connected plates attachedto said temple and end-piece to hinge the two together, a pair ofspacedapart fastening spurs on the temple plate imbedded into saidtemple located to straddle said longitudinal opening therein to assistin preventing a relative movement of said temple and plate.

4:. A temple hingefor an ophthalmic mounting comprising a pair ofpivotally connected plates to hinge the temple member to the end-pieceof the frame, a stop lip at the joint end of said plates, andspaced-apart portions of the lip on one of said plates being turned backto form imbedding fastening spurs.

5. A temple hinge for an ophthalmic mounting comprising a pair ofpivotally connected plates to hinge the temple member to the end-pieceof the frame, a single rivet for binding each plate in position, a stoplip at the joint end of said plates, and spacedapart portions of the lipon one of said plates being turned back to form imbcdding fasteningspurs to assist said rivet to prevent relative movement of the hingeplate and the part to which it is fastened.

In testimony whereof I affix my signatu e.
